3 Claims. (or. 20-69) My invention relates to sealing devices and moreparticularly to sealing devices for use in connection with sashes andsash frames.

One of the principal objects of my invention is to provide a sealingdevice fashioned in a man-v ner to permit free movement of a window'sashwithin a frame while at the same time effective ly sealing thesashrelative to the frame to prevent the entrance of air-between therelatively sliding portions thereof. 7

Another object of my invention is to provide a device of the abovedescribed character capable of easy attachment to window constructionsalready in use without modifying the same. a

A further object of my invention is to provide a window sealing devicewhich, while simple in construction, durable in use and efiicient inoperation, is so constructed and arranged to permit the free adjustmentof the sashes relative to the frame. I

Other objects and advantages will be'apparent from the followingdescription, appended claims and annexed drawing. I

Referring to the drawingwherein like reference characters designate likeparts throughout the several views: I

Figure 1 is an interior elevation of a window construction illustratingmy invention applied thereto. I

Figure 2 is an exterior elevation of the window construction illustratedin Figure 1 with my invention applied thereto.

Figures 3 and 4 are detail sectional views-taken on thelines 3--3 and4--4 of Figure '1 respective- In practicing my invention I provide awindow frame 5 having top, side and bottom frame elements, 6, l and 8respectively, each formed with sash receiving channels 9. Upper andlower sashes l and I l are positioned within the frame, each having topand bottom rails l2 and I3 respectively and connecting side railsMslidable in the channels 9. Said rails are provided with outer andinner faces l and IB respectively. The

" top rail I2 of the upper sash l0 and the bottom rail [3 of the lowersash l I are seated withinthe channels 9 of the top and bottom frameelements respectively when the sashes are in closed position asillustrated in Figures 1 and 2 of the draw- The lower rail l3 of theupper sash l0 and the upper rail I2 of the lower sash H are each.provided with lower faces H and the inner faces 16 thereof are adjacenteach other when the sashes sashes and the frame.

l A strip l8 of pliable material, for-instance felt, is secured to eachof the outer faces l5'of the.

, side rails of both of the sashes: and to the outer faces of the upperand lower, rails l2 and I3 of the upper and lowerjsashes respectively..Each stripis fashioned with rightl'angularly disposed engages theadjacent frame elementof the frame for sliding engagementtherewith.

Elongated members 2|, for instance metal 7 strips, are fashioned withright angularly disof pliable material, for instance felt,is secured tothe lower face I! of the lower rail 13 of the upper =A Er cr me-114+sections l9 andZll. --The sectionZdOf each :stri 1 sash Ill and engagesthe inner-face it of the upper rail l2 of the lower sash II and asimilar shaped member 25, for instance a metal strip. overlies the strip24 and likewise conceals the same from view. I

The sections I9 of the strips l8, sections 22 of the members 2!, strips24 and members25 are.

' exposed ends of the respective strip s'and maintain the strips in acompact contactual or gasketed condition, relative to the frame andrails, thereby effecting a seal between the frame and sasheswhen thesashes are in closed position and preclude creeping or expansion of thestrips without the members due-to relative movement of the From theforegoing it will be apparent that the members effectively conceal thefelt strips from view and that the end sections of the respectivemembers coact therewith to maintain the strips in gasketed conditionrelative to the rails and I frame for preventing the'passage of air fromone side of the sashes to the other when the sashes are in closedposition relative to each other and the window frame.

What I claim is:

'1'. A device of the'character described, comtive movement between saidsections and said frame, said members each fashioned with oppositelydisposed end sections spaced from said frame and said sash and partiallyembracing exposed end faces of said strips for concealing the same fromview and maintaining the strips in gasketed condition relative to saidframe and rail whereby to effect a seal therebetween and to precludecreeping of said strips without said members upon movement of said sashwithin said frame.

2. A device of the character described, comprising, in combination, awindow frame fashioned with opposed sash receiving cham'lels, a sashhaving sash rails slidable in said channels, strips of pliable materialappressingly mounted on said rails and having right angularly disposedsections appressingly engaging said frame, mem' bers having rightangularly disposed portions and covering the entire outer faces ofsaidstrips, means securing said members and said strips to said rails ina manner to permit relative movement between said sections and saidframe, said members each fashioned with oppositely and right angularlydisposed'end portions spaced from said frame and said sash and partiallyembracing the exposed end faces of said strips for maintaining thestrips in a compact contactual condition relative to the frame and railswhereby to effect a seal between the frame and sash when in closedposition and to preclude creeping of the strips without said members dueto relative movement of said sash and said frame.

3. In a window construction, the combination of a window frame fashionedwith Opposed frame members having sash receiving channels, a sash havingrail members slidable in said channels, strips of pliable materialengaging said frame and rail members, retaining elements covering theouter faces of said strips, and means securin one of said elements andone of said strips to one of said members adjacent each of said channelsand in a manner to permit relative movement between said sash and saidframe, said elements fashioned with end sections spaced from said frameand rail members and partially embracing exposed end faces of saidstrips for concealing the same from view and maintaining the strips ingasketed condition relative to said frame and rail members whereby toeffect a seal therebetween and to preclude creeping of said stripswithout said elements by movement of said sash within said frame.
